Control strategy for improving the power flow between Home Integrated Photovoltaic System, Plug-in Hybrid Electric Vehicle and Distribution Network

This paper deals on control strategy and analyzing power flow between home integrated photovoltaic system (PVS), plug-in hybrid electric vehicle (PHEV) and distribution network. The neutral point clamp (NPC) multilevel inverter is the main element that allows interfacing between the different energy sources and receptors. The combination of synchronous reference frames (SRF) and indirect control algorithms applied to NPC, has allowed the system working in On and Off-grid condition for providing a continuous and uninterruptible power supply, for minimizing losses and managing effectively the power flow. The integrated PVS is supposed to satisfy a power load demand in the normal condition of solar irradiation. A PHEV is charging from PVS or grid and could supply power in case of off-grid emergency situation. An onboard bidirectional charger is modeled and controlled by sliding mode algorithm in order to ensure a secure charging and discharging of PHEV batteries. The system is tested for power factor correction and voltage regulation along with harmonic elimination. The performance of the system is validated using MATLAB software with its Simulink and power system blockset toolboxes.
